A and B run around a circular track. A laps B in the middle of the 5th lap. i.e. when A has run four and a half laps he has covered a distance which is 1 lap greater than that covered by B's.
Therefore, when A runs 9/2 laps, B runs 7/2 laps.
This is same as saying when A runs 9 laps, B runs 7 laps.
i.e in a race that is 9 laps long, A can give B a start of 2 laps.
So, if the race is of 3000 metres long, then A can give B a start of
(2/9)×3000= 666.67 metres.
